We're dividing 821616 by 84 
We want to divide 821616 by 84.

On to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 84

Advancing to step 2:
82 divided by 84 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 84

On to step 3:
When dividing 821 by 84, we get 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 756 away from 821, we end up with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 84

Moving on to step 4:
84 goes into 656 7 times with a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 588 from 656, we get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 84

Going ahead to step 5:
681 divided by 84 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
If we take 672 away from 681, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 84

Moving on to step 6:
96 divided by 84 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 9781.0
The remainder is 12 after subtracting 84 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 9781.1
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
When dividing 360 by 84, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 9781.14
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 84 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 9781.142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 84, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 9781.1428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
If we divide 480 by 84, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9781.14285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 9781.142857
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 9781.1428571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
When dividing 360 by 84, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9781.14285714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 9781.14285714 with a remainder of 2.4e-08.
